Maxiwarm combined thermal accumulator

Category: Hot water > Combined thermal accumulators

Code: MXW

Thermal accumulator for the storage of heating water produced from continuous or discontinuous heat sources; instant production of Sanitary Hot Water by means of a AISI 316L stainless steel high efficiency corrugated heat exchanger.
Available in:

only accumulation
accumulation + primary fixed coil heat exchanger
accumulation + two fixed coil primary heat exchangers

The thermal fluid contained in the external puffer and in the primary heat exchangers must operate “closed loop” (without oxygen), this to avoid corrosion.
